1. A method comprising steps of:

  • connecting, via a computing device, to a first Bluetooth Low Energy (BLE) unit at a location, said connection comprising identifying a beacon emitted from said first BLE unit and an identifier of the first BLE unit;

    determining, via the computing device, a signal strength associated with the first BLE unit from said beacon;

    emitting, via the computing device, a first signal, said first signal having a first timestamp associated with said emission and a second timestamp associated with reception by said first BLE unit;

    receiving, at the computing device, second signal emitted from the first BLE unit, said second signal having a third timestamp associated with the emission from the first BLE unit and a fourth timestamp associated with said reception of the second signal;

    determining, via the computing device, a distance between the computing device and the first BLE unit, said distance based upon an aggregated distance based on the first, second, third and fourth timestamps; and

    storing, via the computing device, said distance in a storage, said distance stored in association with said signal strength and the identifier of the first BLE unit.
